1 Claim. 1

My invention relates to improvements in scrubbing and washing machinesfor the lids of cheese boxes. 7

By Way of premise, the cheese box lids with which my invention isconcerned are round, large Wooden covers with wooden strips on one sideand are hard to handle and scrub clean by hand, as is the commonpractice.

With the foregoing in mind, it is the primary object of my invention toprovide a simply constructed rotary brush, scrubbing and washing machinewhich will thoroughly clean such lids on both sides quickly and thussave considerable time and'labor in rendering the lids sanitary and fitfor repeated use.

Another object is to provide a machine for the above purpose which iseconomical to service,

operate and manufacture and not liable to get out of order underprolonged use.

Other and subordinate objects, within the pur View of my invention,together with the precise nature of my improvements will be readilyunderstood when the succeeding description and claims are read withreference to the drawings accompanying and forming a part Of thisspecification.

In said drawings:

Figure 1 is a view in plan of my improved machine in the preferredembodiment thereof;

Figure 2 is a view in side elevation of the same;

Figure 3 is a, fragmentary view in vertical transverse section taken onthe line 3-3 of Figure 1 and drawn to a larger scale;

Figure 4 is a view in transverse section taken on the line 4-4 of Figure3.

Referring to the drawings by numerals, my improved machine comprises arectangular, skeleton frame 1 including a pair of upper angle iron sidebars 2 supported at the ends thereof by legs 3, of tubular stock pipe,connected in pairs on opposite sides of the frame I by longitudinallower side members 4, also of stock pipe. A cross pipe member 5 connectsthe legs at opposite sides of the frame I at what constitutes the frontof the machine, and a similar rear cross pipe 6 connects the legs atopposite sides of the machine at what constitutes the rear of themachine.

A pair of upper and lower cylindrical vertically aligned brushes H), Hextend transversely of the frame I in the transverse center thereof, the

brushes, having flexible bristles l2 extending from a tubular core [3.The brushes it, it are spaced slightly apart, and parallel, with theupper brush I0 slightly smaller in diameter than the lower brush l l fora purpose presently explained. lJhe brushes III, II are mounted asfollows:

The core l3 of the upper brush I0 is fixed on a shaft [4 having its endsjournaled in bearings I5 bolted, as at I6, to short angle bars llsupported at the ends thereof above the side bars 2 parallel therewithby vertical rods l8 threaded into the side bars 2 with retaining nuts 19thereon. The lower brush H has its core l3 fast on a shaft 26 journaledat its ends in bearings 2| suitably fixed on the side bars 2.

A drive for the brushes in, II rotate the same in the same direction asindicated by the arrows in Figure 3, and the upper smaller brush l0faster than the larger one H to feed a cheese box lid 22 therebetweenfrom the front to the rear of the machine. The brush drive comprises asuitable electric motor 25 supported on a platform 26 suitably bolted,as at 21, on one of the side members 4. Twin belts 28 extend from a twinpulley 23 on the armature shaft 30 of the motor 25 around a twin drivepulley 3| on one end of the shaft [4 of the upper brush l0. One run ofthe belts 28 drives a twin pulley 32 on one end of the shaft 20 of thelower brush H. The twin pulley 32 is larger than the twin pulley 3! sothat the lower brush H is driven slower than the upper brush l0 and thespeed of the upper brush [0 is considerably faster than that of thelower brush. As will be clear, the arrangement of the belt drives thebrushes H), H in the same direction.

A pair of laterally spaced, parallel lid supporting rollers aresupported in a common horizontal plane at what constitutes the front ofthe machine, in front of the brushes I0, H and by a pair of horizontalangle bars 36 at the sides of the machine in which the ends of saidrollers 35 are journalled, said bars 36 being supported above the sidebars 2 by vertical rods 31 welded, as at 38, to said bars 2 and threadedinto the angle bars 36 with retaining nuts 33 thereon.

A pair of lid supporting rollers 43, like the rollers 35 are supportedat what constitutes the rear of the machine, in the rear of the brushesill, I! by angle bars 4| like the bars 36 supported in the same mannerby vertical rods 42. As will be understood, the rollers 35, 40 aredisposed in a common horizontal plane to support the lid 22 horizontallyand spaced substantially equidistantly between the cores l3 of thebrushes 56, H.

A metal brush guard of inverted trough shape covers the upper brush infor confining water fed to the upper brush and by means presentlydescribed, and said guard has its ends 46 resting on a pair of canvassplash sheets 41, 48 depending from the bars ll with upper edgesunderlying the bearings I and secured to said bars I! by said bearings,the sheet 4'! being similarly secured under one of the bearings 21 withthe shaft extended therethrough. The sheet 48 is hung from the side bars2 by rope loops 49 and is similarly secured to the lower member 4 byloops 56. The sheet 41 on the side of the frame I opposite the motor islonger than the sheet 41' to protect the belts 25 in a manner which willpresently be clear.

A metal water catch trough 5| underlies the lower brush II with thelower portion of said brush II running therein and has its ends 52loosely suspended on the shaft 20 of said lower brush II.

A Water feed pipe 54 is extended through one end of the splash guard isto extend longitudinally along and over the top of the upper brush iiito spray water downwardly into the upper brush it. Above the upper brushIt? the water pipe 5 has a portion perforated for spraying onto saic.brush. A coupling on the pipe 55 provides for securing thereto a pipe 52leading from a suitable source, net shown, of hot water under pressure.A branch pipe 58 extends from the pipe 5:3 to the lower portion of oneend 52 or" the catch trough 5! to feed water into said trough. Asuitably valved drain pipe 59 depends from the bottom of the catchtrough 5i for draining water therefrom.

The operation of the described invention will be readily understood. Thelids 22 are pushed over the rollers and in between the brushes I3, ii.As the edge of a lid 22 enters between said brushes Ii II, the brushesrotating in the direction indicated by the arrows in Figure 3 feeds thelid rearwardly over the rollers ed. The upper brush it} receives and issaturated with hot water from the pipe 54 and the catch trough filled toa predetermined depth of hot water to saturate the lower brush iirunning therein. The saturated brushes I 0, E I act against oppositesides of the lid 22 with a scrubbing or scouring and washing action tothoroughly clean the same. Since the upper brush is rotates faster thanthe lower brush H, it tends to feed the lid 22 relative to the lowerbrush II so that the lid moves ahead relative to the lower brush I Iwhich rotates oppositely relative to the direction of feed of the lid 22whereby to facilitate scrubbing, or scouring action of the lower brush II against the bottom side of the lid 22 which is usually coated fromexposure to cheese and is difficult to clean. The catch trough catcheswater drained from the upper brush I!) after the lid 22 has passed saidbrushes. The valved drain pipe 59 provides for draining the catch troughas the occasion may require. The splash sheets 47, 48 confine the wateragainst escape at the sides of the machine and, as will be clear, thebelts 28 being outside the splash sheet 4'1, said sheet protecting thesame against being splashed by water.

The foregoing, will, it is believed, sufiice to impart a clearunderstanding of my invention, without further explanation.

Manifestly, the invention, as described, is susceptible of modification,without departing from the inventive concept, and right is here reservedto such modification as falls within the scope of the appended claim.

Having described my invention, what is claimed as new is:

In a machine for scouring and washing box a frame comprising a pair ofbars having supporting legs, a pair of upper and lower cylindricalbrushe: the upper one smaller than the lower one, means rotatablymounting said brushes on said side bars transversely of the frame inparallel relation for receiving a lid between the rollers at oppositesides of the pair of bru has for supporting a lid fed between the apower drive for rotating said brushes in the direction and the upper onefaster than the lower brush to cause the upper brush feed the lidrelative to the lower brush with a scouring action by both brushesagainstopposite of the lid, and means for saturating said brushes withwater for washing the lid.
